1N5231B_T50R

Single Zener Diodes Overview

The onsemi 1N5231B_T50R is a single general-purpose Zener diode with a nominal voltage of 5.1 V and a maximum power dissipation of 500 mW. It features a 5% tolerance, operates within a temperature range of -65°C to 200°C, and utilizes an SOD-27 through-hole package. Key electrical parameters include a test current of 20 mA, a maximum Zener impedance of 17 Ω, and a maximum reverse leakage current of 5 μA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a nominal 5.1 V reference level
• Supports high-temperature operation up to 200°C for demanding environments
• Utilizes a glass-passivated silicon junction for reliable performance

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection in low-power electronic systems
• General-purpose clipping and clamping applications

Single Zener Diodes Procurement Notes

Verify the specific suffix _T50R against official datasheets to confirm tape-and-reel packaging details. Ensure the manufacturer designation matches onsemi specifications. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Single Zener Diodes Selection Notes

Select this component when a 5.1 V Zener voltage is required with a 500 mW power rating. The SOD-27 through-hole package is suitable for standard PCB mounting. Consider the 17 Ω impedance and 5 μA leakage current for circuit sensitivity requirements.

Single Zener Diodes Part Context

This device belongs to the 1N52 series of Zener diodes manufactured by onsemi. The series offers various voltage options within a standardized form factor. The 1N5231B variant specifically targets the 5.1 V application segment with defined tolerance and thermal characteristics.

Single Zener Diodes Replacement Considerations

Compatible substitutes include the 1N5231B from other manufacturers such as Microchip or TDK, provided they meet the same 5.1 V, 500 mW, and 5% tolerance specifications. Verify package compatibility and thermal ratings before substitution.
